Sidalcea calycosa is a species of flowering plant in the mallow family known by the common names annual checkerbloom, checker mallow, and vernal pool checkerbloom.

The plant is endemic to California, along the North Coast and adjacent Northern California Coast Ranges from Mendocino County to Marin County in the northern San Francisco Bay Area, and in sections of the western Sierra Nevada foothills from Butte County south into Tulare County.
